T0 all 11i/Loin, 'it may concern Be it knownthat l, NORMAN W. CUMMINS, a citizen of the United States, residing in the city of Bridgeport, county of Fairfield,v State of Connecticut, havel invented certain new and useful Improvements in `Grease- Cups; and I do declare the following to be a full, clear, and exact description of the invention, snch as Will enable others skilled in the art 'to Which'it appertains to make and use the same. v

This invention relates to certain new and useful improvements in grease cups and pertains more particularly to the means in a force feed cup for preventing retrograde movement of the cap' that constitutes the feeding element. l f

The prin'iary object of the present invention is to provide simple, inexpensive, novel and improved means for the purpose of preventing retrograde movement of the grease cup, and to this end the invention consists essentially in the provision of anon-rotating leather or similar disk which is exteriorly threaded and which, by frictional Contact with the cap, prevents rotation thereof, eX- cept when considerable force is applied to the cap in order'to rotate same to effect feed of the grease. i

In the drawings: Figure l is aside elevation, partly broken away, and in section of 'the invention; F ig. 2 is a section on the line 2--2 ofFig. l; Fig. 3 is a section on the lino 3--3 of'Fig. l; and Fig. Lis a detached perspective view of the leather disk.

The body l of the grease cup has an interiorly threaded, reduced lower end 2, the upper end of the body being formed with an annular ange 3. c A. reinforcing member fi has an interiorly extending flange 5 which is formed with an opening that conformably receives the body l, which latteris of hexagonal, shape' in cross section. 'lhe upper free end portion of the reinforcing member inwardly so to engage on the top face of the iange 3 of body l, as indicated at 6, whereby the flange 5' and the inwardly forced portion or flange 6, clamps the flange 3 between said flanges 5 and 6, as depicted in Fig. l. The peripheral portion of the reinforcing member 4 is externally threaded, and engages with the interior threads of a cap 7.' A leather or similar disk 8 is formed ber 4. The -disk'S is held in engagement withthe flange 5 by means of teats 10 which latter are formed by shaving or cutting the angular portions of the hexagonal body, and forcing said portions firmly against the under face of the disk 8, whereby the latter is held in position at a plurality of points 'Without the use of any additional element, since i the fastening means constitutes an integral part of the body 1.

As above stated, the leather disk exerts sufficient friction upon the threads of the cap 7 so as to hold the latter against backward movement without the exertion of considerable lmanual force. A further and important decided advantage, Which the invention presents, is that the teats 10 may, by means of a punch, be forced toward the flange 3 to any extent desired so as to increase the degree of compression of the disk 8, with the result that the frictional or binding engagement that said disk exerts on the threads of cap 7 is increased, inorder to exert any desired pressure upon said threads. Should the friction that the disk exerts upon the threads of the cap 7 be lessened, for any reason, it will be obvious that by forcing the teat-s toward the flange 5, the disk 8 can -be compressed to any desired extent so as to exert necessary frictional contact with -the threads of cap 7, to attain the purpose of the invention.'

1What is claimed is:

l. In a grease cup, an angular body formed of malleable material, an exteriorly threaded reinforcing member secured 'to the Y body and havingan inwardly extending base fiange, an interiorly threaded cap engaged over and with said threads of the reinforcing member, a leather or similar disk externally threaded and provided with an opening that receives the body, said disk having its upper face engaged with the flange' of the reinforcing member and having,- itsV threads frictionally engaged With the threads of the cap, the angular portions of the body having displaced material engaged soV Q nossjvo with the under face of the leather disk to hold same at a plurality of spaced points and against the flange of the reinforcing Amember. f

In a grease cup, a body formed of 4lmilleable material lhaving an angular crossseeton and an abutment adjacent .its'upper end, a leather or similar disk having an opening which receives `the body and is held from rotation by the latter, an nterorly threaded cap on the body, said disk having its periphery threaded and frctionally engaged-with the threads of the cap, and a series of spaoed independent means integral with the body and engaged with the under face of the disk to ho d same against the abutment, said means being capable of being fereibly moved against the disk to govern the extent of compression of the latter.

3 ln a grease cup; a body formed of malleable material having an' angularerosssection and 'an abutment'adjacentts upper end, a. leal-ller or similar disk having an opening which receives the body and is held from rotation bythe latter, an nterorly tln'eade its Peri, .Y gaged .vlt" he threads el tile cap ad tei/EES integral W the body and engageftl 'with me under face el' tbe te C d plurality et points to bold same n pesiton, said teat-s be' g capable of `erebly moved ag; press the latter.

el.' In a grease enla7 a. bedy formed of malleable material, a cap tlxeaded overv the body, any abutment on the body,l a disk' on the body engaged with said abutmentand having a threaded periphery to/fretonally engage the ln'eads of the Cap, and teats integral 'with 'che body and being ycapable of being lforcibly moved to encrage the disk to hold same against saidY abu'tl ent.

ln testimony whereof lI affix my signature in presence of two witnesses.
